The quotient of two numbers is the result of the division of the first listed number by the second listed number.

Also, the product of two numbers is the result of the multiplication of the first listed number and the second listed number.
But because, multiplication operation is comutative [the result is the same irrespective of which is listed first].
We can say that the product of two numbers is the result of the multiplication of the two numbers irrespective of which is listed first.

Given the expression
$\frac{x-2}{x^2+9}$
Here, x - 2 is being divided by $x^2+9$ .

Therefore, the accurate descripton of the given experession is the quotient [becuase of division] of x - 2 [the numerator or the dividend] and $x^2+9$ [the denominator or the divisor]
(option A).

Graph the function. For the function whose graph is shown below, which is the correct formula for the function? y = –x – 1 y = x

rusak2 [61]

You forgot to mention the graph.
So, I make the graph of both given functions and you will compare your graph with them.

First, y= -x-1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,-1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

Second, y= x+1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

Witcch point lies on the line of the point-slpoe equation y-2=5(x-6)

Marina86 [1]

Answer:

See below.

Step-by-step explanation:

<u>Simplify</u>

y - 2 = 5(x - 6)

y - 2 = 5x - 30

y = 5x - 28

Find the midpoint of the segment with the given endpoints.

Ksju [112]

The mid-point for given endpoints is (4,3)

Step-by-step explanation:

a mid-point is the point on a line segment that divides it into two equal portions.

If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:

$M = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

given

(x1,y1) = (9,9)

(x2,y2) = (-1,-3)

$M = (\frac{9-1}{2}, \frac{9-3}{2})\\\\=(\frac{8}{2}, \frac{6}{2})\\\\=(4,3)$

The mid-point for given endpoints is (4,3)

The expected values of the binomial distribution are given as follows:

1. 214.

2. 21.

3. 31.

<h3>What is the binomial probability distribution?</h3>

It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

For item 1, the parameters are:

p = 3/7, n = 500.

Hence the expected value is:

E(X) = np = 500 x 3/7 = 1500/7 = 214.

For item 2, the parameters are:

p = 0.083, n = 250.

Hence the expected value is:

E(X) = np = 250 x 0.083 = 21.

For item 3, the parameters are:

p = 1/13, n = 400.

Hence the expected value is:

E(X) = np = 400 x 1/13 = 31.
